未调用 Firestore 触发器

Question

I have a firestore set up like this:

And i call onUpdate as explained in Cloud Firestore triggers docs.

functions.firestore.document(`users/{userId}`).onUpdate((change, context) => {
    console.log("it's working")
});

I click on button to increase the balance but nothing gets logged (the balance gets increased though.)

What am i doing wrong?

When you create a Cloud Function Trigger, you should see its presence inside your Firebase Console. If it is not there, then it is not being exported which is a requirement for it to being triggered.

exports.myFunction = functions.firestore...
